Abstract
A plasma display device (10) is provided with circuitry (50) which modifies at least the R and B color component signals so as to compensate for the displacement of the display elements or sub-pixels for each color component relative to each other in the array. Surprisingly, this increases the ratio of wanted signal to alias spectrum. The modification is effected by an interpolator comprising transversal filters (31R, 31B). The circuitry can be combined with down-converters (52) when a high definition source is used. In this case a transversal filter (31G) is also included for the G color component signal.
